A Multivariate Generalizability Theory Approach to Standard Setting.

Generalizability theory (G theory) allows researchers to assess the many sources of variance inherent in complex standard setting procedures involving the determination of cut scores. The flexibility of G and D studies provides a way to conceptualize and quantify the results of different standard settings once the universe of admissible observations and the universe of generalization are defined. The current article applies a multivariate single-facet design for estimating standard errors of cut scores. For practical purposes, several multivariate D study designs are used to investigate what effect various panel sizes and test lengths have on the precision of the standard setting process. The current study demonstrates the advantages and usefulness of multivariate G theory in determining the accuracy of cut scores in practical applications of standard setting procedures.
